To all whom it may concern: v

Be it known that we, SAMUEL T. WELL AN, JOHN W. SEAVER, and CHARLES H. WELL- MAN, citizens of the United States, and residents of Cleveland, county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Hoisting, Conveying, and Storing Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In the said annexed drawings, Figure I represents a front elevation of our improved hoisting, conveying, and storing apparatus, showing also a coal-pocket and gas-producer. Fig. II represents a vertical transverse sectional View of the coal-pocket, roof, and mechanism for automatically opening and closing doors in the said roof of the coalpocket, also showing a gauntree-crane in elevation, together with a car, block and fall,-

bucket, and a railroad-car upon a track laid parallel to the apparatus. Fig. III represents an enlarged detail partial sectional view of one rail-bed girder, showing also a portion of the crane; and Fig. IV represents a top plan view thereof.

The conveying portion of the apparatus consists of the crane A, constructed of canta livers a, supported upon legs a, provided with wheels which run upon rails B upon girders B.

From the lower chords a of the trusses forming the cantalivers is supported a trolley-track a upon which travels a trolley O, carrying the block and fall D, to which is attached the bucket E. By hanging the track from the bottom chords the trusses may be transversely braced, as shown, without interfering with the travel of car 0. The cantalivers, and hence the track of, extend laterally beyond and above the girders B.

A trolley-Wheel F, attached to the Crane, engages a trolley-wire G, connected with suitable electrical current-generatin g apparatus, which furnishes the power for suitable motors for operating the crane, trolley-car, and'block and fall.

The trolley-wire is supported and inclosed by a guard H, which is supported by the sides of the coal-pocket J, the said guards preventing any injury by accident to the wire and also preventing short-circuiting of the current by the possible Contact of the fall in swinging to and fro. The said guard H consists of a bent bar, one of whose parallel sides h is riveted or bolted to the girder B. The other side h is thus brought to a perpendicular position and has attached the angle b whose unattached side extends inwardly, to which is in turn fastened the angle h whose unattached side extends downwardly, the whole forming an inverted trough, to the inner and upper side of which are hung insulators for supporting the wire.

The upright girders B form the lateral sides or containing-walls of the pockets, and upon the upper surface are laid and suitably secured the rails 13, upon which run the wheels of the crane. The girders thus form the railbed for the crane and include between them the storage-space of the bin, forming the sole confining sides thereof.

The coal-pocket J is supported on suitable posts and is provided with a roof j, which at intervals is provided with door-openings j and doors 7' The said doors slide upon rollers in runways j which incline with the roof in opposite directions. Suitable ropes or chains j 4 are fastened to said doors, pass over pulleys 7' and are joined and connected with one arm of the levers j the said levers being pivoted on the outside of one of the girders B. One lever is provided for each door-opening, and each lever is formed with a curved arm j 7 and an army' to which is attached a weight j A stop 3' is disposed and fastened on the girder so as to maintain the curved armin a position such that the chord of the arc of said curved arm will be about horizontal, the highest point in the curved arm being brought about opposite the middle of the door-openings.

A downwardly-projecting arm a, provided at its extremity with a roller a is attached to the crane and is so arranged that the roller will engage the curved lever to depress it, counteracting the effect of the weight j 9 and permitting the doors to roll down the runways and to uncover the door-openings when the crane is directly over the said openings. On the further movement of the crane the levers are released,and the weight is permitted to act and to reclose said doors. The said arm is formed with a hinge and provided with suitable means wherebyit may be thrown out of the path of the said levers and pass without opening the doors.

A spring may be substituted for the weight 3' The floor of the coal-pocket is provided at intervals with chutes j, controlled by the valves and levers 9' The said chutes discharge into a gas-producer K.

The crane is provided with hooks a", which curve under the outer and upper angles of the girders B, so that should the traverser tip the said hooks will engage the said angles and prevent the overturning of the apparatus.

Other modes of applying the principle of our invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed,provided the principles of construction set forth, respectively, in the following claims are employed.

We therefore particularly point out and distinctly claim as our invention 1. The combination with a storage-bin having girders forming the sides thereof, of a traveling crane, said girders forming the railbed for said crane, and including the storagespace,"substantially as set forth.

2. The combination with a storage'bin having upright girders forming the sides thereof, of a traveling crane, said girders forming the rail-bed for the crane and including the storage-space, and provided with a transverse track and carrying means for traveling upon said track, the latter extending laterally beyond and above said storage-space, substantially as set forth.

The combination of a crane,a coal-pocket having a roof covering provided with an opening, and a door covering said opening and means for opening said door, said crane provided with means for engaging and operating said opening means, substantially as set forth.

4. The combination with a crane, of a coalpocket, provided with a roof-covering having an opening and a doorcovering said opening, said coal-pocket provided with door-opening means, and said crane provided with means for engaging and operating said opening means, substantially as set forth.

5. The combination with a crane, of a coalpocket provided with a roof-covering having a succession of openings and doors covering said openings, said coal-pocket provided with door-opening means for opening each door, said crane provided with means for engaging and operating said door-opening means to open each door on the passage of the crane over its respective opening, substantially as set forth.

6. The combination with a gauntree-crane of a coal-pocket provided with roof-covering, said roof covering provided with door-openings; doors over said openings; the sides of said coal-pocket being provided with levers connected with said doors, said crane provided with a projecting arm adapted to engage said levers to open said doors on the passage of the crane over the door-openings, substantially as set forth.

7. The combination with a gauntree-crane of a coal-pocket provided with a roof-covering, said roof-covering provided with door-openings, doors over said openings, adapted to be opened by gravitation, the sides of said coal-pocket being provided with pivoted and weighted levers connected by suitable means with the said doors, the weights adapted to depress one end of said levers and to operate to close said doors; the crane being provided with a projecting arm whereby, on the passing of the said crane above said door-openings, the free end of the levers are depressed and the effect of the weights counteracted, whereby the doors are opened by gravitation, substantially as set forth.

8. The combination of doors mounted upon oppositely-inclined runways, a pivoted lever provided at one end with a weight, the other end being connected by suitable means with the said doors, whereby the weight operates to hold said doors in the uppermost limit of travel in said runways, a traveling crane or conveyer provided with a projecting arm provided with a roller adapted, when passing, to engage and depress said lever, counteractin g said weights and permitting the said door to slide downwardly by gravitation and open door-openings beneath said doors, and 011 passing to release said lever and to permit said weight to reclose said door, substantially as set forth.

In testimony that we claim the foregoing to be ourinvention We have hereunto set our hands this 29th day of July, A. D. 1896.
